We are pleased to announce the release of the newly developed AFLEET Tool. This tool has been designed for Clean Cities stakeholders to estimate petroleum use, greenhouse gas emissions, air pollutant emissions, and cost of ownership of light-duty and heavy-duty vehicles using simple spreadsheet inputs.
For more information and to download the software, check out the AFLEET Tool page.

GREET 2 2014

Added six new vehicles for both baseline and lightweigting models, with different material compositions.

To fully evaluate energy and emission impacts of advanced vehicle technologies and new transportation fuels,
the fuel cycle from wells to wheels and the vehicle cycle through material recovery and vehicle disposal need to be considered.
Sponsored by the U.S. Department of Energy's Office of Energy Efficiency and Renewable Energy (EERE), Argonne has developed a
full life-cycle model called GREET (Greenhouse gases, Regulated Emissions, and Energy use in Transportation). It allows researchers
and analysts to evaluate various vehicle and fuel combinations on a full fuel-cycle/vehicle-cycle basis.

The first version of GREET was released in 1996. Since then, Argonne has continued to update and expand
the model. The most recent GREET versions are the GREET 1 2014 version for fuel-cycle analysis and GREET 2 2014 version for vehicle-cycle analysis.

GREET was developed as a multidimensional spreadsheet model in Microsoft Excel. This public domain model is available free of
charge for anyone to use.

For a given vehicle and fuel system, GREET separately calculates the following:
